The Viking Steel Bungee was developed from customer requests:

"I have a flying CH-701 at present and was always wondering how to improve the bungee on the nose wheel strut.  I have added a collar to the strut to keep it from total collapse but am leery of the keeping the prop out of the dirt if the bungee "shits the bed".  I noticed your picture on the Zenith Builders site and backed through all the available pictures plus the ones you show on your site.  I am curious about more detailed pictures showing how your system works -  and what modifications are necessary to install your system.  Right now the bungee holds the nose strut down against a aluminum "L" bracket which causes friction in the rudder system. Also torquing the bungee as the rudder move adds to the system stiffness - ala' the 701 rudder that doesn't want to center.  I couldn't tell from your pictures how your system works thus my email.  Thanks in advance for you response."

Very good questions and you show a clear understanding of the limitations of the original system.
Basically, the steel bungee works in reverse of the original rubber bungee, yet the suspension load is transferred to the original cross tube.  The Preloading of the spring is handled internal to the spring, using an adjustable rod, providing no force to the airframe while in flight. The ramp effect of the original plastic material has been milled away and the steering arms now ride on a flat surface.
